Summary
This was a Phase I/II, single-center, dose-escalation study. 177-Lutetium-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid-cG250 (177-Lu-DOTA-cG250) was administered at a starting dose of 30 mCi/m^2 of 177-Lu (fixed dose of 10 mg cG250) and escalated in increments of 10 mCi/m^2 of 177-Lu in sequentially enrolled cohorts according to a standard 3 + 3 design until determination of the maximum tolerated dose (MTD). The primary objectives were to determine the safety, targeting, and dosimetry of 177-Lu-DOTA-cG250 in subjects with advanced renal cell carcinoma. The secondary objective was measurement of tumor response according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0.Phase:

Criteria
Inclusion Criteria:1. Subjects with proven advanced and progressive renal cell carcinoma (RCC) of the clear
cell type.
2. At least one evaluable lesion < 5 cm.
3. Karnofsky performance status ≥ 70%.
4. Laboratory values obtained < 14 days prior to registration:
- White blood cells (WBC) ≥ 3.5 × 10^9/L
- Platelet count ≥ 100 × 10^9/L
- Hemoglobin ≥ 6 mmol/L
- Total bilirubin ≤ 2 × upper limit of normal (ULN)
- Aspartate aminotransferase and alanine aminotransferase ≤ 3 × ULN (< 5 × ULN if
liver metastases present)
- Serum creatinine ≤ 2 × ULN
5. Negative pregnancy test for women of childbearing potential (urine or serum).
6. Age over 18 years.
7. Ability to provide written informed consent.
Exclusion Criteria:
1. Known metastases to the brain.
2. Untreated hypercalcemia.
3. Metastatic disease limited to the bone.
4. Pre-exposure to murine/chimeric antibody therapy.
5. Chemotherapy, external beam radiation or immunotherapy within 4 weeks prior to study.
Limited field external beam radiotherapy to prevent pathological fractures was
allowed, when unirradiated, evaluable lesions were present elsewhere.
6. Cardiac disease with New York Heart Association classification of III or IV.
7. Subjects who were pregnant, nursing or of reproductive potential and were not
practicing an effective method of contraception.
8. Any unrelated illness, e.g., active infection, inflammation, medical condition or
laboratory abnormality, that in the judgement of the investigator would have
significantly affected the subject's clinical status.
9. Life expectancy < 6 months.
